MPEG-2TS 流嵌入控制数据的设计，设计的要求是用控制数据替换MPEG-2 TS 流中的空帧-MPEG-2TS control data stream embedded in the design, the design requirements is to control data to replace MPEG-2 TS stream of the air frame

ＡＤ转换代码，主要练习，没有具体的功能可以实现的，因为只是一部分(AD conversion code, practice, no specific function can be realized, because only part)

RTL8369开发资料，包括手册，图纸，Layout说明等等(RTL8369 development information, including manuals, drawings, Layout Guide.)

Conduct a digital system ( electronic lock ) using hierarchic methodology . An electronic lock is a device that allows access or opening of a system , as long as the key or combination to enter match with which it is predefined in said lock .

说明：  PIC单片机学习软件及其资料，入门到精通(PIC MCU learning software and its information, entry to proficiency)

基于FPGA的数字钟的设计，外部时钟32MHz，通过分频器得到秒脉冲，用于正常工作时的计数脉冲。通过分频还得到一个5ms的脉冲，用于按键的消抖（具体原理可见程序）。输入的信号有三个：1.时钟信号2.校时模式设置按键3.校时调整按键，输出通道6位数码管。共有：校时模块，24计数的小时计数模块，60计数的分钟计数模块，60计数的秒钟计数模块。

verilog语言编写的jtag（边界扫描模块），初学的时候可以看看(verilog language jtag (boundary scan module), a novice when you can look)

8对于输入密码锁的键，假设重置后七个灯显示" 0"，并且使用sw1、sw2、sw3 3，只需按任意sw1、sw2、sw3，将使七个灯显示值相加" 1

使用VHDL语言实现对快速傅立叶变换算法的实现，并通过仿真验证其正确性。(Using VHDL language implementation for the realization of fast Fourier transform algorithm, and its correctness is validated by computer simulation.)
